Milkdown is a flexible, open-source editor that lets you write and edit Markdown in a simple, visual way, just like you see it in apps such as Typora. It is built using powerful tools like ProseMirror and Remark, and everything in Milkdown works as a plugin, so you can add or remove features easily. You can customize its look and feel to match your app, and it supports real-time collaboration for team editing. This means you get a reliable, easy-to-use editor that fits your needs and grows with your projects, making writing and sharing documents smoother and more efficient[1][2][4].

🪐 Near the center of the Small Magellanic Cloud, scientists have discovered a magnetar called SXP 1062 with a magnetic field so strong it can reshape atoms and trigger intense X-ray outbursts. Magnetars are a rare kind of neutron star—ultra-dense remnants of exploded massive stars—whose magnetic fields are trillions of times stronger than Earth's and can even change the properties of empty space around them, making these cosmic magnets among the universe's most extreme phenomena. ✨

🪐 The star VY Canis Majoris, located about 3,900 light-years from Earth, is one of the largest known stars in the universe—so huge that if placed at the center of our solar system, its surface would reach beyond the orbit of Jupiter. This red hypergiant loses mass at an incredible rate, creating vast clouds of dust and gas that make it appear as a dim, shifting patch in telescopes rather than a sharp point of light. ✨

🪐 In the spiral galaxy Messier 81, astronomers use precise observations of variable stars called Cepheids to confirm that light travels at a constant speed—299,792 kilometers per second—across millions of light-years. By timing the changes in these stars' brightness, scientists can measure vast intergalactic distances, showing that the universal speed limit of light holds true even when crossing the immense gulf between galaxies. ✨

The Moon takes about 29.5 Earth days to go from one sunrise to the next. Daylight lasts around 14.75 days, and night also lasts about 14.75 days. This long day and night happen because the Moon spins slowly and moves around Earth at the same time. We always see the same side of the Moon because of this. 🌕🌑

The 1967 Outer Space Treaty says no country can own the Moon, but rules about mining are still unclear. Working on the Moon could also be dangerous for human health.
The Moon has water ice and rare metals that could help future space missions. But mining the Moon will damage its surface and spread potentially harmful dust. 🌕🚀

During Apollo 10, a piece of poop floated inside the spaceship. The astronauts al denied it was theirs. In zero gravity, everything floats. 🚀💩

Pluto is slightly bigger than Russia.
Pluto has a surface area of about 17.65 million km².
Russia has an area of about 17.1 million km².
Some sources say otherwise because of old measurements or rounding.
Those sources are wrong.
